Since it's been converted to oil, it's likely missing the cast iron grates, linkage mechanism and shaker handle. Also all or part of the ash pit is likely gone. In the early '70's I was given a similar 3 section cast iron boiler. At the time I was able to buy everything to convert it back to coal except the ash pit door. I still have it anyone interested? Matt?
